Yes, it can. You can work this out by using Pythagoras' theorem (a² + b² = c²).

Add up the squares of the two smaller numbers (8² + 15²) = 289

Square root the sum of the two squares and see if it matches the bigger number. (√289) = 17.

2x - 2y = 22 find the value of y when x equals 2
Vika [28.1K]

Answer:

y=-9

Step-by-step explanation:

If x equals 2, then we can substitute that into the equation, resulting in the equation 2*2-2y=22

We can solve for multiplication first:

4-2y=22

Then we can subtract four on both sides, canceling out the four on the left side:

-2y=18

Now to isolate y, we divide both sides by -2, resulting in the solution:

y=-9

Hope this helps!

PLEASE HELP I NEED HELP !!!!!!!! The graph of a line passes through the two points (-2, 1) and (2, 1). What is the equation of t
MrRissso [65]

Answer:

y - 1 = 0

Step-by-step explanation:

We know that Equation of a line is given by,

y - y₁ / x - x₁ = y₂ - y₁ / x₂ - x₁

Let A(-2,1) and B(2,1)

x₁ = -2 ; x₂ = 2 ; y₁ = 1 ; y₂ = 1

Substituting the values,

y - 1 / x - (-2) = 1 - 1 / 2 - (-2)

y - 1 / x + 2 = 0

y - 1 = 0

Svetradugi [14.3K]

Answer:

45 3/10 miles per hour

Step-by-step explanation:

Distance travelled by the car = 30 1/5 miles

Time taken = 2/3 of an hour

Average speed = distance travelled / time taken

= 30 1/5 miles ÷ 2/3 of an hour

= 151/5 ÷ 2/3

= 151/5 × 3/2

= (151 * 3) / (5 * 2)

= 453 / 10

= 45 3/10 miles per hour

Average speed = 45 3/10 miles per hour
